The proteinase-activated receptors (PAR) PAR1 and PAR2 mediate responses to thrombin and trypsin-like proteases, respectively. Both receptors are expressed on endothelial cells where they have been reported to transduce a similar set of intracellular responses. In cultured human umbilical vein endothelial cells (HUVEC), we observed a marked...

Prolonged ERK/MAPK activation has been implicated in neuronal cell death in vitro and in vivo. We found that HEK293 cells, recently reported to express neuronal markers, are exquisitely sensitive to long term ERK stimulation. Activation of an inducible form of Raf-1 (Raf-1:ER) in HEK293 cells induced massive apoptosis characterized by DNA...

Cortactin is an actin-binding Src substrate involved in cell motility and invasion. In this study, we sought to examine the prognostic importance of cortactin protein expression in head and neck squamous cell carcinoma (HNSCC). To do so, cortactin and EGF receptor (EGFR) expression was retrospectively evaluated by immunohistochemistry in a...

: Glioblastoma multiforme (GBM) are highly invasive and angiogenic malignancies with a median survival time from diagnosis of <15 months. Previous work has revealed robust overexpression of fibronectin (FN) mRNA in GBM, although immunohistochemical staining of FN in these tumors is typically associated with the angiogenic vasculature. Here we...
